The green indicator located on the top of the module (Vaux) indicates the relay power
supply status. When the power supply is operating correctly the indicator stays on,
whereas if the power supply is disabled the indicator light is turned off.
The red LED below it (Vs) is the pickup indicator. This led remains lit as long as the
relays detects a fault condition.
The red indicator labeled TRIP is a trip indicator that remains lit after a trip and can be
turned off by pressing the RESET button once the cause of the trip has disappeared.
The microswitches on the front panel are divided into two groups, the upper group of
microswitches is used to select the trip level while the lower group is used to select the
timing.

The relays are calibrated before leaving the factory, therefore it is not necessary for the
user to calibrate them.
Changing between overvoltage and undervoltage in the single phase models is
performed through the use of jumpers as shown in figure 8:
